如何将“旧的 spring mvc 控制器与 jsp”和“vaadin7 ui”集成在一起

我正在尝试将 vaadin 与我的 spring mvc 应用程序集成。 我有一些带有 jsp 文件的 url，spring mvc 控制器使用它们 例如 ： mysite.com/spring/ mysite.com/spring/examples mysite.com/spring/examples/1.jsp

我想在此路径中添加 vaadin： mysite.com/vaadin/MainUI

这是我的 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1"
  xmlns="http://java.sun.com/xml/ns/j2ee" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_3_1.xsd"
      metadata-complete="true">

  <display-name>vaadin-spring</display-name>

  <!-- Turn off productionMode (off by default). Setting productionMode=true disables 
       debug features. In when this is off, you can show debug window by adding ?debug to 
       your application URL. Always set this true in production environment. -->
  <context-param>
    <param-name>productionMode</param-name>
    <param-value>false</param-value>
    <description>Vaadin production mode</description>
  </context-param>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>

  <servlet>
    <servlet-name>vaadin-spring</servlet-name>
    <servlet-class>com.vaadin.terminal.gwt.server.ApplicationServlet</servlet-class>
    <init-param>
      <param-name>application</param-name>
      <param-value>com.practice.vaadin_spring.VaadinSpringDemoApplication</param-value>
      <description>Vaadin application class to start</description>
    </init-param>
  </servlet>

  <servlet-mapping>
        <servlet-name>vaadin-spring</servlet-name>
        <url-pattern>/vaadin/*</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>vaadin-spring</servlet-name>
        <url-pattern>/VAADIN/*</url-pattern>
    </servlet-mapping>

  <!-- spring -->
  <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>spring.profiles.active</param-name>
            <param-value>local</param-value>
        </init-param>
  </servlet>
  <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

这是我的弹簧主控制器：

@Controller
@RequestMapping("/")
public class MainController {

    @RequestMapping(value = "{jspFile}")
    public String map(@PathVariable String jspFile) throws IOException {
        return jspFile;
    }

    @RequestMapping(method = RequestMethod.GET)
    public String map1() throws IOException {
        return "index";
    }

}

这是 github 中的工作示例（修复后）https://github.com/prilia/IntegrationSpringMvcVaadinUI https://github.com/prilia/IntegrationSpringMvcVaadinUI

因此，经过一番尝试后，我最终遇到了 JSP 编译异常，我认为这是合理的，因为您在 github 上提供了测试示例。 到目前为止，这是我所做的：

web.xml

<servlet-mapping>
  <servlet-name>spring</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

主控制器.java

@Controller
@RequestMapping("/")
public class MainController { ...

我添加了 spring-servlet.xml

<bean name="spring" class="org.nli.deposit.controller.MainController" />

现在看来它解析了网址：

http://localhost:8080/springMvcTest/ http://localhost:8080/springMvcTest/转到 JSP

http://localhost:8080/springMvcTest/vaadin http://localhost:8080/springMvcTest/vaadin前往瓦丁

它只是在 JSP 编译期间崩溃，但这完全是另一个问题。 尝试您的完整项目并告诉我！
